This is a riddle which describes and animal. In the Tibetan region, many households keep cats. Cats can often be seen lying in warm spots near the hearth or in a patch of sunshine.  When lying down, warm and comfortable, cats may purr. This purring is also known in Tibetan as “reciting scriptures”.  This riddle connects tthe chanting of scriptures with the possession of a good heart, and therefore, the posession of a good heart with cats. This riddle then asks about another aspect of the cat’s nature. When a cat sees a mouse, it may jump on the mouse and immediately kill and eat it without compassion. In this way, a cat demonstrates its two natures: a kind-hearted mantra chanter and a grasping old demon.
